If any of you NA Guys are going to supercharger I have a Supercharged Pump setup with jumper wire to have both pumps on at the same time, that is plug and play. Thats good to about 425-450HP (Same pump setup as a 02-03 HD).

what is the HD install kit? I have a lightning and i'm assuming that this will work for me also?

Thanks

Just a quick question.... WHat is the benefit of this mods for me at about 380 HP w/mods runnin 93 octane fuel. I would consider if there is benis( which im sure there are I just dont know what they are)

[Harley#356]

Not the expert on this, but i would say maybe a bit more stabilized pressure since you're getting close to the limit on the stock pumps, where on the walbro's its more in its operating range isntead of the high side of their limit. i'd say stock pumps is totally fine for 380, but if you remember at the dyno day, SVT2000 with the silver L was running out of fuel at right around a little over 400 hp 500 tq. Mason swapped out the fuel filter but it still wasnt getting enough fuel to go beyond those #'s, even though his other mods were capable of beyond that.

ACWalsh on the other hand had 255's and bigger injectors already, so his truck was still fine on fuel at 405/495.

i'll let bill or somebody else post up more on what they know, but either way for 185, its a hell of a deal to get a set!

Not an expert either......

6lb lower stock upper, 13+lbs of boost 400/500 and pumps and stock pumps doing just fine here. FP Guage shows good.

COuple guys here still on stock pumps and similiar setups.

I know after I put the ported blower on, that My Dual Walb's will be going in for extra measure,

[BigBill]

The stock pumps are 130LPH. They are 260lph, thats good for about 450HP. Depens exactly depending on A/F and timing and what type of fuel.

I dont recomend going to 100% on anything ESPECIALLY fuel related, because if the engine goes lean, especially on a stock block. BOOM.

So I say if you are pushing over 400WHP on a harley its a good upgrade. Or if your fuel pumps are bad, because the stock pumps are $300 as an assembly. So for $185 to get new pumps, that have 800HP worth of fuel, why not?

The only down side is that pumping the fuel harder will heat it up more, thats just a fact. But the Walbro's are very efficent, so the outlet temps are generally less than 15 degrees hotter.

[BigBill]

This GB is almost over.. Get them while I still have them. If you plan to run over 450hp or have over 80K miles I recomend changing the fuel pumps. These are much less expensive than the factory replacements and the pumps are good for 1000HP as a pair.

So at 430HP and 506TQ. with 14+lbs. boost, 17* timing and 11.8 A/F would it be safe to say I am on the edge??
Hey , Bill maybe a trade for a Panhard Bar...

[huot5]

Hey bill pm'd ya. If you still have the GB, I'm down for a set-up. with stainless "y". thanks.

Thaks Bill. I do have a question. I saw an add, on fuel rails with adjustable FPR which specifically mention this upgrade. Does the stock rail and regulater have issues with this up grade?
Before I install....
